The teenagers sped off in their car when the man went to his front door.
"I was pretty traumatised," he said. "I didn't really want to say anything to him in case it was the wrong thing to say while we were in the car."
Western Bay of Plenty tactical response manager Inspector Karl Wright-St Clair confirmed there had been an incident where teenagers had been allegedly held at gunpoint and kidnapped.
The armed offenders squad searched a Parkvale address about 8am yesterday in relation to the incident, he said.
One man was taken into custody.
Police were last night unable to provide further details regarding whether an arrest had been made and what, if any, charges had been laid.
